According to a message posted Friday on Smith’s website, the singer-songwriter underwent emergency surgery for appendicitis on Friday. According to the message, Smith was “out of surgery and doing well.”

Three shows planned for this weekend were affected, including tour stops in Jacksonville, Fla., and Houston. Tonight’s show at the Amphitheater at the Wharf was rescheduled for Friday, July 20.

According to Birmingham-based Red Mountain Entertainment, the show’s promoter, tickets purchased for the original date will be honored on the new date. Smith’s website indicated that the rescheduled show will have a different slate of support acts than the original date, which was to have featured Blackberry Smoke and Marc Broussard.

According to Red Mountain and Smith's website, ticketholders also have the option of obtaining full refunds at the outlets where they purchased their tickets; the deadline for refunds is midnight on July 18. For information, call the Wharf box office at 251-224-1020.
